“…Mesocarp fiber (MF), obtained after the oil extraction process of fresh fruit, offers an extra benefit to plastic film manufacturers. MF contains 3–8% remnant oil in its pressed fiber (Majid et al., 2012; Yunos et al., 2015) and has the potential to be used as an alternative lubricant in cold work metal forming (Hafis et al., 2013). In this sense, if MF is used as a filler in the biocomposite system, the oil residue can act as a lubricant to assist uniform fiber dispersion across the polymer matrix during polymer processing.…”

Oil palm mesocarp fiber (MF) holds the potential to be used as a filler in polymeric biocomposite systems. To further improve the dispersion and interfacial adhesion between the fiber and polymer matrix, MF was treated with sodium hydroxide (NaOH) at different concentrations (1%, 3%, 5%, 8% and 10%) and soaking times (1 h, 4 h, 8 h, 24 h and 48 h). The effects of NaOH solution and soaking duration on the oil residue, thermal stability and surface morphology of the MF were investigated. It was found that the soaking time had a prominent effect on the oil residue content compared to the NaOH concentration. Fourier transform infrared spectra demonstrated that alkaline treatment decreased the peak intensities of the carboxyl group and alkene of the fatty acid (oil) at 1630-1700 cm -1 . Meanwhile, the clean and smooth surface of MF was revealed by scanning electron microscopy, indicating the removal of noncellulosic components. The treatment also reduced the degree of crystallinity of MF, as reflected by its melting temperature (T m ) and heat of melting (ΔH m ), as measured by using differential scanning calorimetry. MF with oil residue is envisioned to improve the fiber dispersion across the polymer matrix during polymer processing.

“…Some of its applications are in food, nutraceutical, and cosmetic industries, and in the production of lubricants, biodiesel, and glycerol [94][95][96]. Some of the extraction methods that can be used to obtain FA are mechanical extraction [97], extraction by supercritical fluids and organic solvent [98], microwave-assisted extraction [99], and supercritical CO 2 extraction [98].…”

This chapter describes the use of carbon dioxide at high pressures as an alternative for the extraction of bioactive compounds in a more sustainable way, addressing some of its physicochemical properties, such as pressure, temperature, density, solvation, selectivity, and its interaction with the solute when modified by other solvents such as ethanol and water. This extraction process is considered chemically "green," when compared to conventional extraction processes using toxic organic solvents.

Green tribology is a new field of greatinterest to a large number of tribologists. This article reviews the latest advances in this area including energy conservation, emission reduction, super-low friction and super-low wear, wind turbines,smart coatings, and fundamentals. Moreover, an overview ofthe future development of green tribology is also presented. Ecological lubricants/fluidsRecently, Holmberg and coworkers [8] demonstrated the global impact of friction on energy consumption, environment and economy through two case studies on passenger cars and paper machines [9, 10]. The authors showed the amount of energy lost to overcome friction and how to improve the energy efficiency of mechanical systems. They concluded that the global fleet of passenger cars used 33% of their total fuel energy annually to overcome friction, and the paper machines on aglobal level used 9.2% of the total energy annually and 32% of the electrical energy of the paper machines to overcome friction. In total, 100 million TJ/a is annually consumed to overcome friction worldwide, which is contributing to the global emission with 7000 million tones of CO 2 annually.Low-dimensional nano-materials with self-lubricating capability (such as MoS 2 , WS 2 , graphite, carbon nanotubes and so on) might be considered as potential anti-friction and wear additives for future engine oil application, owing to their unique size, shape, chemistry and structure morphology. In 2013, Erdemir [11] reviewed the latest research trends in 0 to 3D selflubricating nano-materials as potential oil additives and their prospects for commercial applications. He concluded that self-lubricating nano-materials with 0 to 3D structural architectures may hold great promise for further enhancing the anti-friction, -wear, and -scuffing performance of future lubricating oils.Considering that the rare-earth fluoride in base oil has good extreme pressure, anti-wear and friction performance,the lanthanum fluoride (LaF 3 ), in particular, displayspromising applications as a lubrication additive. Zhang and coworkers [12] evaluated the RECEIVED
